. OF LEEBDAM, THE NETHERLANDS GLASS BUILDING-STONE, TILE OR LIKE BUILDING Em! Application filed October 24, 1929. Serial No. 402,116.

The invention relates to a method for making a wall of glass building-stones, tiles or like building-elements.

When building a wall of glass buildingstones or tiles, the stones or tiles are placed upon and adjacent each other, with the insertion of mortar between them. In general relatively stifi mortar is required in order to prevent the stones ortiles from sinking through the mortar under the influence of their own weight and to avoid that the glass building-stones or tiles come in direct cons tact with each other, which gives easy rise to fracture. .Furtherit is necessary to use rapidly hardening mortar as otherwise during building one would have to wait to long for the-hardening of the mortar of the stones or tiles already put in place.

In order to remove these drawbacks and budding-stone in accordance with Fig. 1, to-

make it possible to use vry'slowly hardening mortar, according to the invention use. is

made of elastic supporting pieces, which are' .inserted between the stones, preferably at the place of the bearing surfaces, which are not visible, that isto say which are not' located at the exterior side. .The said elastic supporting ieces e. g. pieces of cork, asphalt, felt, lino eum, asbestos, metal or the like, may

be secured beforehand on the bearing surfaces of the glass building stones, e. g. be lued thereon.- The elastic bearing-pads 't the sinking through the mortar ofthe stones automatically in the desired degree. At the same time irregularz-niasonry is avoided and also fracture ofstones through correction'of the saidregul'arities.

I By reason of the, fact thatlitj -is now possible' to use a'very slowly hardening mortar,

stresses or force's actingin thebuilding, in

which the glass stones ortiles have been used,

will'be compensated by tlie not yet entirely hardened mortar and the elastic supporting? pieces, whereby iracture of the or tiles is much reduced.

The drawin' illustrates the invention by way of examp e in .two embodiments.

I claim: 1. A building block formed of vitreous material, and having a plurality of bearing sur-' faces on the top side, some of which bearing surfaces are visible when the blocks are placed in a wall, and some of which are invisible at such times,-and elastic bearing material on the said surfaces which are invisible, for receiving the cooperating bearing surfaces of adjacent blocks to prevent fracture of the blocks.

v 2. Abuilding block formed of-vitreous material and having bearing surfaces arranged on its upper surface, the said bearing surfaces comprising separated, ,lon 'tudinallyaligned, raised surfaces inset wit respect to the edges of the said top surfaces, and elastic bearing material between the said raised surfaces and'adjacent the transverse extremities thereof, to receive the cooperating bearing surfaces of adjacent building blocks without fracture thereof, at the same time remaining substantially invisible from the exterior 3. A hollow buildin block formed of vitreous material and aving bearing surfaces arranged on its upper surface, the said bearing surfaces comprising separated, longitudinally-aligned, raised surfaces inset with respect to the edges of the said top surfaces, and elastic bearing material between the said raised surfaces and adjacent the transverse extremities thereof,-to receive the cooperating bearing surfaces of adjacent building blockswithout fracture thereof, at the same time remaining substantiall invisible from the exterior when mounte in a wa 4. A building block formed of vitreous mawhen'mounted in a wall.

terial comprising bearing surfaces arranged in planes substantially at right arigles to the plane of the wall surface in which the block is to be mounted, certain of the hearing surfaces being visible from the exterior and certain others of the bearing surfaces bein invisible from the exterior when the bloc is mounted in the said wall, and elastic bearing material mounted on the bearing surfaces which are invisible, in order to receive the cooperating bearing surfaces of adjacent building blocks without fracture of the blocks. 7

5. A wall comprised .of building elements of vitreous material, the said elements each having bearing surfaces thereon, some of which are visible when the blocks are placed in a wall, and some of which are invisible at such times, and elastic bearing material located between the invisible bearing surfaces and the cooperatin bearing surfaces of adjacent elements, wl iereby to prevent fracture of the elements.

In testimony whereof I afiix my signature.
